To make the objects, technical solutions and advantages of the presentdisclosure more clear, the present disclosure will be described infurther detail with reference to the accompanying drawings, and it isapparent that the described embodiments are only some, but not all,embodiments of the present disclosure. All other embodiments obtained bythe ordinarily skilled in the art based on the embodiments of thepresent disclosure without paying any creative effort shall be includedin the protection scope of the present disclosure.

The shapes and sizes of the components in the drawings are not to scale,but are merely intended to facilitate understanding of the contents ofthe embodiments of the present disclosure.

As shown in FIG. 1, in an embodiment of the present disclosure, there isprovided a backplane 1 which, when used in a display panel, may besecured to a middle frame 2 in the display panel to form a framestructure of the display panel.

Specifically, as shown in FIG. 1, the backplane 1 of the embodimentincludes a bottom plate 11, and a skirt 12 connected to edges of thebottom plate 11. At least part of the skirt 12 is provided with aclamping member 3 for securing the backplane 1 to the middle frame 2 toform the frame structure. The clamping member 3 is provided with adismounting structure 31 for disengaging the clamping member 3 from theskirt 12 of the backplane 1 under an external force so that thebackplane 1 is separated from the middle frame 2.

It should be noted that the skirt 12 of the backplane 1 is arranged atthe edges of the bottom plate 11 of the backplane 1, and the skirt 12extends upward in a direction away from the bottom plate 11. The bottomplate 11 may include a polygonal bottom plate, and the clamping member 3is provided on the skirt 12 of at least one side of the bottom plate 11.For example, the bottom plate 11 may be a rectangular bottom platehaving the skirt 12 on four sides, and the clamping member 3 is disposedon the skirt 12 of at least one side of the rectangular bottom plate,which may be specifically designed as needed and is not limited herein.The following description will be given by taking the example where thebottom plate 11 of the backplane 1 is rectangular, the edges of therectangular bottom plate have the skirt 12 on four sides, and theclamping member 3 is disposed on the skirt 12 on one side.

In the backplane provided by the embodiment, since the dismountingstructure 31 is provided on the clamping member 3 for connecting themiddle frame 2 to the backplane 1, when the backplane 1 needs to beseparated from the middle frame 2, the clamping member 3 can beseparated from the skirt 12 of the backplane 1 when an external force isapplied to the dismounting structure 31 of the clamping member 3,thereby accomplishing the separation of the middle frame 2 and thebackplane 1.

Optionally, as shown in FIG. 1, in the backplane provided by theembodiment, the skirt 12 of the backplane 1 includes a first sidesurface 121 and a second side surface 122 extending along a lengthdirection of the skirt 12 and arranged oppositely.

Referring to FIGS. 1, 2 a and 2 b, FIGS. 2a and 2b are schematicstructural views of the clamping member 3 in FIG. 1, and the clampingmember 3 includes a first side part 32 and a second side part 33arranged oppositely, and an upper part 34 of the clamping member 3connected between the first side part 32 of the clamping member 3 andthe second side part 33 of the clamping member 3. The first side part32, the second side part 33 and the upper part 34 of the clamping member3 form a generally U-shaped sectional structure to receive the skirt 12of the backplane 1. When the clamping member 3 is clamped onto the skirt12 of the backplane 1, the first side part 32 of the clamping member 3contacts the first side surface 121 of the skirt 12, the second sidepart 33 of the clamping member 3 contacts the second side surface 122 ofthe skirt 12, the upper part 34 of the clamping member 3 is connectedbetween the first side part 32 of the clamping member 3 and the secondside part 33 of the clamping member 3, and the first side part 32, thesecond side part 33 and the upper part 34 of the clamping member 3 forma clamping structure that clamps the skirt 12 of the backplane 1therein.

Further, as shown in FIGS. 2a and 3, FIG. 3 is a sectional side viewtaken along a direction A-B after the backplane 1, the middle frame 2and the clamping member 3 in FIG. 1 are secured together. The first sidepart 32 of the clamping member 3 is provided with a clamping tonguestructure 35, and the first side surface 121 of the skirt 12 is providedwith a groove 123. When the clamping member 3 is clamped onto the skirt12 of the backplane 1, the first side part 32 of the clamping member 3contacts the first side surface 121 of the skirt 12, and the clampingtongue structure 32 on the clamping member 3 may be clamped into thegroove 123 on the first side surface 121 of the skirt 12, i.e., theclamping tongue structure 32 may be engaged with the groove 123 tosecure the clamping member 3 on the skirt 12, so as to prevent theclamping member 3 from falling off from the skirt 12. As shown in FIG.3, for example, the clamping tongue structure 32 extends obliquely fromthe first side part to the second side part and into the U-shapedsectional structure.

Further, as shown in FIG. 2b , the second side part 32 of the clampingmember 3 is provided with a clamping elastic sheet 36 for securing thebackplane 1 to the middle frame 2. As shown in FIG. 4, for example, theclamping elastic sheet 36 extends obliquely from the second side part ina direction away from the first side part.

Specifically, as shown in FIGS. 2b and 4, FIG. 4 is a sectional sideview taken along a direction E-F after the backplane 1, the middle frame2 and the clamping member 3 in FIG. 1 are secured together. Referring toFIG. 2b , the second side part 32 of the clamping member 3 may beprovided with a plurality of clamping elastic sheets 36 (e.g., twoclamping elastic sheets 36), and a connection part disconnected from theplurality of clamping elastic sheets 36 and located between two adjacentclamping elastic sheets 36. If the second side part 32 of the clampingmember 3 is provided with two clamping elastic sheets 36, then thesecond side part 32 of the clamping member 3 further has a connectionpart 37 located between and disconnected from the two clamping elasticsheets 36. The disconnected arrangement means that two adjacent clampingelastic sheets 36 on the second side part 32 of the clamping member 3are spaced apart from each other, but the clamping elastic sheets 36 andthe connection part 37 on the second side part 32 of the clamping member3 are both connected to the upper part 34 of the clamping member 3, andthe dismounting structure 31 is located on a side of the connection part37 away from the second side surface 122.

Optionally, as shown in FIG. 2b , in the backplane 1 of this embodiment,the dismounting structure 31 may include various shapes, such as a tab.The tab to serve as the dismounting structure 31 is disposed on theconnection part 37 of the clamping member 3. When the backplane 1 needsto be separated from the middle frame 2, the tab 31 on the clampingmember 3 is pressed by an external force so that the clamping member 31is separated from the skirt 12 of the backplane 1, thereby completingthe separation of the middle frame 2 and the backplane 1.

Optionally, as shown in FIG. 2b , in the backplane 1 of this embodiment,a plurality of (e.g., two) dismounting structures 31 may be provided onthe connection part 37 of the clamping member 3. If the dismountingstructure 31 is a tab, two tabs are disposed on the connection part 37,and the two tabs may be symmetrically disposed along the connection part37 of the clamping member 3 about a midline in a direction parallel tothe bottom plate 11 of the backplane 1. When the backplane 1 needs to beseparated from the middle frame 2, the two tabs on the connection part37 of the clamping member 3 may be pressed at the same time by anexternal force so that the clamping member 3 is separated from the skirt12 of the backplane 1, thereby completing the separation of the middleframe 2 and the backplane 1. Since the two tabs as the dismountingstructures 31 are symmetrically disposed on the connection part 37, theforce on the clamping member 3 can be more uniform when the two tabs arepressed so that the clamping member 3 can be more easily separated fromthe skirt 12 of the backplane 1.

Optionally, as shown in FIG. 3, in the backplane 1 of this embodiment,an inner width L of the clamping member 3 is greater than a thickness Wof the skirt 12 of the backplane 1, and the difference D between theinner width L of the clamping member 3 and the thickness W of the skirt12 is greater than an engagement depth S of the clamping tonguestructure 35 of the first side part 32 of the clamping member 3 into thegroove 123 in the first side surface 121 of the skirt 12, that is, thedifference D between the inner width L of the clamping member 3 and thethickness W of the skirt 12 satisfies:D=L−W>S

where the inner width L of the clamping member 3 is a distance betweenthe first side part 32 of the clamping member 3 and the connection part37 of the clamping member 3 in a direction perpendicular to the firstside part 32.

Referring to FIGS. 3 and 5, after the clamping member 3 is clamped ontothe skirt 12 of the backplane 1, i.e., after the clamping tonguestructure 35 of the first side part 32 of the clamping member 3 isengaged with the groove 123 in the first side surface 121 of the skirt12, if the difference D is greater than the engagement depth S, adistance H (H≈D) between the second side part 33 of the clamping member3 and the second side surface 122 of the skirt 12 is greater than theengagement depth S of the clamping tongue structure 35 into the groove123. Referring to FIG. 5, if it is desired to separate the clampingmember 3 from the skirt 12, the second side part 33 of the clampingmember 3 may be moved toward the second side surface 122 of the skirt 12by pressing the dismounting structure 31 on the connection part 37 ofthe clamping member 3, i.e., applying an inward (in a direction from thesecond side part 33 of the clamping member 3 toward the second sidesurface 122 of the skirt 12) force F1 to the dismounting structure 31 sothat the second side part 33 of the clamping member 3 is moved in adirection toward the second side surface 122 of the skirt 12 to make thesecond side part 33 of the clamping member 3 attach to the second sidesurface 122 of the skirt 12. As the second side part 33 of the clampingmember 3 attaches to the second side surface 122 of the skirt 12, thefirst side part 32 of the clamping member 3 is also moved in a directionaway from the first side surface 121 of the skirt 12, which in turndrives the clamping tongue structure 35 on the first side part 32 of theclamping member 3 to move in a direction away from the first sidesurface 121 of the skirt 12. As a result, the clamping tongue structure35 may be separated from the groove 123, that is, the clamping tonguestructure 35 and the groove 123 are no longer engaged with each other.If the backplane 1 and the middle frame 2 provided in the embodiment areconnected by the clamping member 3 to form a frame structure, when thebackplane 1 needs to be separated from the middle frame 2, thedismounting structure 31 on the second side part 33 of the clampingmember 3 may be pressed by pressing the middle frame 2 since the middleframe 2 is sleeved outside the backplane 1. Thereby, the clamping tonguestructure 35 and the groove 123 may be separated from the engaged stateby pressing the dismounting structure 31 of the clamping member 3.Meanwhile, a force F2 is applied to the middle frame 2 in an upwarddirection (a direction pointing away from the bottom plate 11 of thebackplane 1 along the second side part 33 of the clamping member 3), andin case that the clamping tongue structure 35 and the groove 123 isseparated from the engaged state, the clamping member 3 may be movedupward along with the middle frame 2 so that the clamping member 3 maybe separated from the skirt 12 of the backplane 1 along with the middleframe 2, thereby completing the separation of the middle frame 2 fromthe backplane 1. Moreover, in the backplane 1 of this embodiment, theinward force F1 and the upward force F2 are required to be appliedsimultaneously to separate the clamping member 3 from the skirt 12 ofthe backplane 1. When the backplane 1 provided in this embodiment isapplied to a display device, since the inward force and the upward forceare rarely applied to the display device simultaneously in daily use ofthe display device, the separation of the middle frame 2 from thebackplane 1 by normal operations of the display device can be avoided.

Optionally, as shown in FIG. 6, FIG. 6 is a sectional side view takenalong a direction C-D after the backplane 1, the middle frame 2 and theclamping member 3 in FIG. 1 are secured together. In the backplane 1 ofthis embodiment, the connection part 37 of the clamping member 3 has afirst hollowed-out portion 371, and the first hollowed-out portion 371is provided with a buckle elastic sheet 372 obliquely extending towardthe first side part 32. When the clamping member 3 is clamped onto theskirt 12 of the backplane 1, the buckle elastic sheet 372 may be abuttedagainst the second side surface 122 of the skirt 12 so that the clampingmember 3 is secured to the skirt 12 of the backplane 1.

Specifically, as shown in FIGS. 2b and 6, the buckle elastic sheet 372may be, for example, an elastic sheet inclined in a direction toward thesecond side surface 122 of the skirt 12, and one end of the buckleelastic sheet 372 closer to the bottom plate is secured to a lower sideof the first hollowed-out portion 371 closer to the bottom plate 11 ofthe backplane 1, while the other end of the buckle elastic sheet 372away from the bottom plate 11 is movable. Further, as shown in FIG. 6, adistance N between the end of the clamping tongue structure 35 away fromthe bottom plate 11 and the end of the buckle elastic sheet 372 awayfrom the bottom plate 11 is smaller than a thickness W of the skirt 12of the backplane 1 so that when the clamping member 3 is clamped ontothe skirt 12 of the backplane 1, the buckle elastic sheet 372 may beabutted against the second side surface 122 of the skirt 12 to securethe clamping member 3 to the skirt 12 and prevent the clamping member 3from fall off from the skirt 12. If the connection part 37 of theclamping member 3 has two dismounting structures 31, the two dismountingstructures 31 may be symmetrically disposed along the connection part 37of the clamping member 3 about a midline in a direction parallel to thebottom plate 11 of the backplane 1, that is, the two dismountingstructures 31 may be disposed at two sides of the first hollowed-outportion 371.

Optionally, the first hollowed-out portion 371 may have various shapes,as long as the buckle elastic sheet 372 can be disposed in the firsthollowed-out portion 371, which is not limited herein. A length of thefirst hollowed-out portion 371 in the direction perpendicular to thebottom plate 11 may be greater than a length of the buckle elastic sheet372 in the direction perpendicular to the bottom plate 11, so as tofacilitate movement of the movable end of the buckle elastic sheet 372.

Optionally, the buckle elastic sheet 372 may include elastic sheets ofvarious shapes, such as rectangular, trapezoidal and triangular elasticsheets. If the buckle elastic sheet is rectangular or trapezoidal, agreater force may be applied to the second side surface 122 of the skirt12 when the buckle elastic sheet 372 abuts against the second sidesurface 122 of the skirt 12, thereby enhancing the securing of theclamping member 3 to the skirt 12. If the buckle elastic sheet 372 istriangular, the second side part 33 of the clamping member 3 can be moreeasily attached to the second side surface 122 of the skirt 12 when thedismounting structure 31 of the clamping member 3 is subjected to anexternal force, thereby achieving easier separation of the clampingmember 3 from the skirt 12. Apparently, the buckle elastic sheet 372 mayalso have other shapes, and may be specifically designed according toactual needs, which is not limited herein.

Optionally, as shown in FIG. 2a , in the backplane 1 of this embodiment,the first side part 32 of the clamping member 3 is provided with asecond hollowed-out portion 351. The clamping tongue structure 35 isdisposed in the second hollowed-out portion 351, with one end closer tothe bottom plate 11 secured to a lower side of the second hollowed-outportion 351 closer to the bottom plate 11 and the other end away fromthe bottom plate 11 being movable. The clamping tongue structure 35 maybe, for example, an elastic sheet inclined in a direction toward thefirst side surface 121 of the skirt 12, the groove 123 in the first sidesurface 121 of the skirt 12 is positioned corresponding to the clampingtongue structure 35, and a bottom of the groove 123 may be an inclinedsurface inclined toward the inside of the skirt 12 with an inclinationdegree corresponding to that of the clamping tongue structure 35.Specifically, the depth of the groove 123 in the first side surface 121gradually increases along a direction in which the first side surface121 of the skirt 12 points away from the bottom plate 11. The higher theinclination degree of the clamping tongue structure 35, the greater themaximum depth of the corresponding groove 123, and thus the greater theengagement amount between the clamping tongue structure 35 and thegroove 123. The greater the engagement depth between the clamping tonguestructure 35 and the groove 123 is, the less possible the clampingmember 3 falls off from the skirt 12.

Optionally, the clamping tongue structure 35 may include various shapes,such as rectangular, trapezoidal and triangular. If the clamping tonguestructure 35 is rectangular or trapezoidal, the movable end of theclamping tongue structure 35 contacts the groove 123 by a larger area sothat the clamping tongue structure 35 is more firmly secured to thegroove 123. If the clamping tongue structure 35 is triangular, when theclamping tongue structure 35 needs to be engaged into the groove 123,the clamping tongue structure 35 is easier to be aligned with the groove123. Apparently, the clamping tongue structure 35 may also have othershapes, and may be specifically designed according to actual needs,which is not limited herein.

Optionally, the second hollowed-out portion 351 may have various shapes,as long as the clamping tongue structure 35 can be disposed in thesecond hollowed-out portion 351, which is not limited herein. A lengthof the second hollowed-out portion 351 in the direction perpendicular tothe bottom plate 11 may be greater than a length of the clamping tonguestructure 351 in the direction perpendicular to the bottom plate 11, soas to facilitate movement of the movable end of the clamping tonguestructure 351.

Optionally, as shown in FIG. 2a , in the backplane 1 of this embodiment,a plurality of second hollowed-out portions 351 and a plurality ofclamping tongue structures 35 may be disposed on the first side part 32of the clamping member 3. For example, there may be two secondhollowed-out portions 351 symmetrically disposed about a midline of theclamping member 3 in a direction parallel to the bottom plate 11. Eachof the second hollowed-out portions 351 is provided with a clampingtongue structure 35, and the first side surface 121 of the correspondingskirt 12 is also provided with two grooves 123 so that the clampingtongue structures 35 may correspond to and be engaged in the grooves 123one by one, thereby securing the clamping member 3 and the skirt 12 morefirmly.

Optionally, in the backplane 1 of this embodiment, the clamping member 3may be made of various materials, such as spring steel, but of course,other materials may also be used, which is not limited herein.

Specifically, as shown in FIGS. 1 and 4, the third side surface 211 ofthe side plate 21 of the middle frame 2 has a convex structure 214. Thenumber of the convex structures 214 corresponds to the number of theclamping elastic sheets 36 on the first side part 32 of the clampingmember 3. The clamping elastic sheets 36 may be elastic sheets inclinedtoward a direction away from the second side surface 122 of the skirt12. When the middle frame 2 is secured to the backplane 1 via theclamping member 3, the clamping elastic sheets 36 are clamped on theconvex structures 214 to secure the relative position of the middleframe 2 and the backplane 1.

Optionally, referring to FIGS. 1 and 4, in the frame structure of thisembodiment, the middle frame 2 may further include an upper plate 22disposed on the third side surface 211 of the side plate 21. The upperplate 22 is located at an edge of the bottom plate 11 of the backplane 1and on the skirt 12 of the backplane 1, so as to block the skirt 12 ofthe backplane 1 and prevent the backplane 1 from falling out of themiddle frame 2.

Optionally, referring to FIG. 4, in the frame structure of thisembodiment, a light shielding part 225 may be further connected on aside of the upper plate 22 of the middle frame 2 away from the sideplate 21, and disposed opposite to the first side part 32 of theclamping member 3.
